@WebServlet("/demo/HttpServlet")
public class HttpServlet extends javax.servlet.http.HttpServlet {
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("getMethod: " +request.getMethod());

        System.out.println("getContextPath: " +request.getContextPath());

        System.out.println("getServletPath: " + request.getServletPath());

        System.out.println("getRequestsURI: " + request.getRequestURI());

        System.out.println("getRequestURL:"+ request.getRequestURL());

        System.out.println("getQueryString:" + request.getQueryString());

        System.out.println("getRemoteAddr: " + request.getRemoteAddr());


    }
